C1000 - Port-isolation

[Hubsi-Smith]

Hello,
we replaced our HP Procurve Switch with a Cisco c1000 Switch for handling all our Internet devices. All Internet devices are in the same VLAN and same port range. The Port Isolation feature of the Procurve switch was great to forbid the direct communincation between the devices. Does the c1000 switch has any similiar or could it be done with ACLs?

Best regards

Hello @Hubsi-Smith,

yes, you can do the same on the c1000 switch. The feature only has a different name.

Cisco calls this a Protected Port and you can configure this setting under "Port Management" --> "Port Settings".
The communication rules for Protected Ports are pretty simple:

• No communication between Protected Ports even if they are in the same Vlan
• Protected Ports are only allowed to communicate with unprotected ports

When you move from HP to Cisco you will notice that there are more features with different names. The protocols are standardized but the naming conventions are not which can lead to confusion.

HTH!
